STAIR-CARPET HOLDER.

Application filed October 28, 1911.

To all whom it may concern Be it known that I, HERMAN GAsLnR, of Canastota, in the county of Madison and State of New York, have invented a certain new and useful Stair- Carpet Holder, of which. the following is a specification.

This invention has for its object the production of a stair carpet holder which is particularly simple in construction, economical in manufacture and highly eficient and durable in use; and is consists in the combinations and constructions hereinafter set forth and claimed.

in describing this invention reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views.

Figure 1 is a sectional view of a portion of a flight of stairs provided with a preferable form of my invention. Fig. 2 is a detail view of the detached carpet holder shown in Fig. 1. Fig. 3 is a detail view of one of the members thereof.

This stair carpet holder comprises means adapted to be secured to the stairs beneath the carpet and formed with a passage, and a member for extending into and interlocking in the passage and for also engaging the outer face of the carpet.

Preferably the means adapted to be secured to the stairs, is located in the angle formed by the tread 1 of one step and the riser 2 of the next step, and as here shown said means is in the form of an angular plate 3 secured in any suitable manner in position, as by screws 1 and having an offset portion 5 spaced apart from the portion of the plate contiguous to the angle thereof, and thereby forming a passage extending parallel to the apex line of the angle of the plate and, as clearly seen in Fig. 1, transversely of the stairs when the plate is secured in position on the stairs. Such offset portion preferably terminates short of the ends of the plate as seen in Fig. 2. 1n the form of plate illustrated in the drawings, the offset portion 5 is provided by integrally securing an additional plate to the base plate 3 but in manufacturing, it is more economical to strike the offset portion from the base plate itself. The member for extending into the'passage and holding the carpet in position comprises a pin 6 for piercing the carpet, the pin having a laterally deflected portion 7 for extending through the carpet when the pin is inserted Specification of Letters Patent.

to its full extent, and a portion overlying the outer face of the carpet, such portion being in the form of a spherical head 8 which presses into the portion of the carpet in the angle formed by the parts 1 and 2. The deflected portion 7 facilitates the insertion of the pin through the carpet and into the passage of the base plate, as if the pin were straight, it would either have to be depressed into the angle of the carpet throughout the entire length of the pin, or if the pin were not so depressed, but were first inserted through the carpet at an angle and then laid over to enter the passage of the base plate 3, the perforation in the carpet made by the pin would be stretched and enlarged. It is to facilitate the insertion of the pin through the carpet and to avoid the enlarging of the hole in the carpet that the deflected portion is provided. lVhen the pin is placed through the carpet until the head approaches the carpet, the deflected portion enters easily and naturally through the hole in the carpet at a suflicient incline to press the head 8 gently into the carpet. Hence the pin is not under a great lateral strain tending to bend or break the same,

and the carpet in the vicinity of the hole therethrough is not subject to a stretching strain. In operation after the plates 3 have been secured in position, the carpet is laid on the stairs and pressed into the angles of the steps and the pins 6 are then forced through the carpet horizontally into the passages.

What I claim is:

1. A stair carpet holder comprising means secured to the stairs beneath the carpet and formed with an elongated passage and a pin for extending through the carpet and through the elongated passage, substantially as and for the purpose described.

2. A stair carpet holder comprising a base secured to the stairs beneath the carpet and formed with a passage and a pin for extending through the carpet and through the passage, the base being formed with a guide for directing the point of the pin into the passage, substantially as and for the purpose specified.

3. A stair carpet holder comprising a base formed with an angle and a passage offset from the apex line of the angle, and a pin for piercing the carpet and extending into said passage, the passage being of less length than the length of the base whereby the angle of the base forms a guide for directing the pin into the passage, substantially as and for the purpose set forth.

4. A stair carpet holder comprising an angular plate adapted tobe secured in the angle formed by the tread of one step and the riser of the next step, the plate beingv formed With an offset portion spaced apart from its angle and thereby forming a horizontally extending passage, and a member having means for extending into the passage and engaging the outer face of the carpet,

gulstantially as and for the purpose speci- 5. A stair carpet holder comprising an angular plate adapted to be secured in the angle formed by the tread of one step and the riser of the neXt step, the plate being formed With an offset portion opposed to its angle forming a transverse horizontal passage, and a pin for piercing the carpet and extending into the passage, the pin having a laterally deflected portion extending through the carpet, and a head overlying the outer face of the carpet, substantially as and for the purpose described.

In testimony whereof, I have hereunto signed my name in thepresence of two attesting Witnesses, at Syracuse, in the county of Onondaga, in the State ofNeW York, this 19th day of October, 1911. I
